Abstract
|
|
|
The objectives of this study were to classify the first permanent molars showing molar-incisor hypomineralization (MIH) on the basis of defect size and to assess differences in the prognoses of restorations performed with different materials.
The first permanent molars with MIH and posteruptive breakdown were categorized into MIH class I, II, and III. After performing restorations, retreatment frequencies were examined according to the defect class and initial restorative material used. Sealants, composite resins, and stainless steel crowns showed the highest survival rates in cases of MIH class I, II, and III defects, respectively
